My 4" lift Recipe (suggestions?)

[xbanone]

So I'm looking for suggestions or recomendations on my lift recipe for my '76 GMC short/step.


My goal is to overhaul the stock very worn suspension (over 200k miles) with a more stable better riding system. I am looking for any suggestions as to what I'm putting together to make my truck more enjoyable to drive. Currently the truck is bone stock 1/2 ton with bilstien HD shocks. The truck rides like the rear suspension is welded solid and the front is worn and sagging. I would like to replace all the springs, bushings and of course shocks.

Here is what I have decided on so far:
4" Tuff Country EZ ride springs (front)
Steering arm
Bilstein shocks (5100)

I need some help on the rear. I could get 4" tuff counrty springs but I'm afraid the ride will be too harsh. A shackle flip is an option but I will still have to replace my rear springs. maybe with something from here:

So what do you all think? Any ideas or suggestions?

Thanks for looking,
Brady
